REGISTER.

SIJECIFICATION forming part of Letters Patent No. 702,936, dated J' une24, 1902.

Application filed March 18, 1901. Serial No. 51,680. tNO model.)

To @ZZ whom, it may concern,.-

Be it known that I, ERNEST C. Fox, a citizen of the United States, and aresident of Cleveland, county of Cuyahoga, State of Ohio, have inventedcertain new and useful Improvements in Registers, of which I herebydeclare the following to be a full, clear, and exact description, suchas will enable others skilled in the art to which it appertains to makeand use the same.

My invention relates to improvements in registers; and the objects ofthe invention are to provide a register adapted for ceiling or partitionwalls, so that the heat from a room warmed by a stove or furnace can beutilized to heat an adjoining room or overhead chamber or shut odtherefrom at will.

My invention consists in the rectangular register and ventilator platesadapted to rest against opposite sides of the partition oroor, in thesquare telescoping tubes connecting them, and spring connections wherebythe plates are secured together, with the details of construction andcombination of the various parts, as hereinafter described, shown in theaccompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 shows a vertical transversesection of the device on line y y, Fig. 2; and Fig. 2 shows a horizontalsection of the same ou line in fr, Fig. 1.

In the views, 1 is the register-bottom, in- 'closing the pivoted slats2.

3 is a square tube of thin metal, as tin, provided with theinwardly-turned iiange 4 all around, which is clamped between theperforated register top plate 5 and the bottom 1.

6 is the ventilator-plate, formed in openwork, which rests against theunder side of the floor or inner side of the partition. To this plate issecured by a flange 13 the square metal' tube 7, which telescopes withinthe tube.

Depending from either side of the registerbox at S are seen the springs9, which are connected at their inner extremities with hooks 10 upon theventilator-plate.

It will readily be seen that the tubes will fill the space in the wallor floor from side to side between the register and ventilator, and thesprings will permit sufcient extension of the tubes to adapt them to anythickness of wall or door, one tube sliding within another, whileholding the register and ventilator firmly in place.

At 12 are seen fingers which point downward from the register-box on theouter side, and at 1l are seen similar lingers upon theventilator-plate, which extend upward opposite to the fingers 12. Theobject of these ngers is to press together the iiat sides of the thinmetal tubes, so that they may not flare apart and admit dust from theinside of the partition or coldvair from between the floors. Thesefingers are curved on their points at 18, so asto slide freely over thesheet metal and press the tubes together.

A removable bottom 14, supported by lugs 15, is formed in theventilator-plate for the purpose of giving access to the interior of therectangular tubes in order to adj ust the springs or to adjust thesliding tubes. This is quite essential to the invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In combination with a register bottom and perforated top plate, arectangularsheetmetal tube provided with a ange secured to said plate, aventilator-plate, a rectangular sheet-metal tube provided with a flangesecured to the ventilator-plate, one of said tubes sliding Within theother, and springs connecting the bottom and ventilator-plate,substantially as described.

2. In combination with a register bottom and top plate thereon, arectangular met-al tube secured thereto, a ventilator-plate, andrectangular tube secured thereto, one of said tubes being telescopedwithin the other, and springs secured to said register-bottom anddetachably connected With said ventilatorplate, substantially asdescribed.

3. In combination, a register bottoni and top plate and aventilator-plate, and' rectangular metal tubes secured to said plates,one sleeved over the other, springsV connecting said bottom andventilator-plate, and fingers arranged to extend on either sid'e of therectangular tubes and secured severally to the bottom andventilator-plate, substantially as described.

4. In combination with a register top plate IOO and bottom, aVentilator-plate, thin telescoping tubes secured respectively to saidregister and Ventilator plates, springs Connecting` said register bottomand ventilator-plate, said ventilator-plate being provided with aremovable central portion, substantially as described.
